EXAMPLE WITH CALCULATION STEPs:

STEP-1

(A) Concrete volume in cum = Volume of casting (Length x Breadth x Height) in m= 10x1x1m (Assume) = 10 cum
(B) Dry Volume Factor for Concrete = 1.54* Wet volume of concrete mix is 54 % higher than dry volume

SETP-2

(C) Concrete wet volume in cum = (A) x (B)= 10 x 1.54 = 15.4 cum

Concrete Ratio = ( Cement :Sand :Aggregate)(Assume) = 1 : 1.5 : 3 i.e. M10-(1:3:6), M15-(1:2:4), M20-(1:1.5:3), M25-(1:1:2), M30-(1:1:1.5), M40-(1:1.62:2.96)
Sum of Ratio = (Cement + Sand + Aggregate)= (1+1.5+3)= 5.5

SETP-3

(CV) Required Cement Volume in cum = (C) x (Cement Ratio/Sum of Ratio)= 15.4 x (1/5.5) = 2.8 cum
Cement in Bag = (CV) / 0.034722 = 2.8/0.034722 cum = 80.64 Bags* Volume of 1 Bag Cement is 0.034722 Cum
(SV) Required Sand Volume in cum = (C) x (Sand Ratio/Sum of Ratio)= 15.4 x (1.5/5.5) = 4.2 cum
Sand in Cft = (CV) x 35.3147= 2.8 x 35.3147 cum = 148.32 Cft* 1 m3 = 35.3147 Cft
(AV) Required Aggregate Volume in cum = (C) x (Aggregate Ratio/Sum of Ratio)= 15.4 x (3/5.5) = 8.4 cum
Aggregate in Cft = (CV) x 35.3147= 8.4 x 35.3147 cum = 296.64 Cft* 1 m3 = 35.3147 Cft

FAQs:

What is Dry Volume Factor for Concrete ?

Dry volume of concrete mix is 54 % higher than wet volume so, When we calculate the mix proportion of concrete it should be multiplied with 1.54, its call Dry Volumn Factor of Concrete

What is Cement, Sand & Aggregate Ratio ?

This is the Volumn ratio of mixing Concrete, This ratio should as per your concrete grade i.e. - M10-(1:3:6), M15-(1:2:4), M20-(1:1.5:3), M25-(1:1:2), M30-(1:1:1.5), M40-(1:1.62:2.96)

What is Water Cement Ratio ?

The water–cement ratio is the ratio of the weight of water to the weight of cement used in a concrete mix.
